I had a slow sideways crash at 5 feet. After witch the gimbal is getting stuck when I pan down to 68 degrees. Once there it becomes overloaded and is stuck. It will then jump to 30ish degrees until finally resting to zero. I have normal movement from +24 to -68. It appears to reach 90 degrees in the start up check. Suggestion? Is it work trying to fix to risk breaking it? I have tried a couple of cans of air duster. It also has unobstructed movement when off.
